Answer this Question
You live 15 blocks (3/4 of a mile) from RACC. Your car is in for service so you decide to walk to class. Walking at a speed of 4 miles per hour, what is the latest time you can leave your home to be on time for your 10:00 am class in Berks Hall?
1) Estimate whether it will take you more or less than an hour?
2) Could you use conversion fractions? Which one(s)?

To find the answer, you need to calculate the time it takes to walk the distance from your home to RACC.
1) Estimate whether it will take you more or less than an hour:
To estimate whether it will take you more or less than an hour, you can use the speed of 4 miles per hour. Since your home to RACC is 3/4 of a mile, you can divide 3/4 by 4 to determine how long it will take you to walk 1 mile.
3/4 mile ÷ 4 miles per hour = 3/16 hours
Since it will take you 3/16 hours to walk 3/4 of a mile, you can see that it will take less than an hour to walk to RACC.
2) Could you use conversion fractions? Which one(s)?
Yes, you can use conversion fractions to solve this problem. One conversion fraction you can use is the conversion from miles to hours. Since the speed is given in miles per hour, you can use this conversion fraction to determine the time it takes to walk a specific distance. In this case, you can use the conversion fraction 1 hour / 4 miles. This means that it takes 1 hour to walk 4 miles.
Using this conversion fraction, you can calculate the time it takes to walk 3/4 of a mile by multiplying it with the distance:
3/4 mile × (1 hour / 4 miles) = 3/4 × 1/4 = 3/16 hours
So, the time it takes to walk 3/4 of a mile is 3/16 hours.
Now, to determine the latest time you can leave your home to be on time for your 10:00 am class, you need to reverse this calculation. Subtract the time it takes to walk from the time of your class:
10:00 am - 3/16 hours = 10:00 am - (3/16) * 60 minutes
To calculate the final time, multiply 3/16 by 60 minutes and subtract it from 10:00 am.
I hope this helps!
